Specific embodiment
The principle and feature of the utility model are described below, illustrated embodiment is served only for explaining the utility model,
It is not intended to limit the scope of the utility model.
In a detailed embodiment, as shown in Figure 1, the J-type fuse of outer cap the brim of a hat flange includes columned porcelain
Tube body 1 is socketed in two copper caps 2 at 1 both ends of porcelain tube body and what is be respectively perpendicular be fixed on porcelain tube body by interference fit respectively
The engaging lug 3 of sheet on the end face at 1 both ends, each engaging lug 3 extend through corresponding copper cap 2, and each copper cap 2 is same with porcelain tube body 1
Axis is set.
As shown in Fig. 2, copper cap 2 includes the brim of a hat body 203 of circular cover 201, round platform ring bodies 202 and circular ring shape.The brim of a hat
Body 203 is coaxially disposed with circular cover 201, and the brim of a hat body 203 is located at the opening one side of circular cover 201.Round platform ring bodies
202, between circular cover 201 and the brim of a hat body 203, the annular end face and the brim of a hat body 203 for connecting circular cover 201 lean on
The annular end face of 201 one side of subcircular cover.
